I think the answer is B. 55. Butbi would cheat to make sure.
(-1)+(-5)+8+(-6)
total number of numbers= 4
total sum= -4
average/ answer= -4/4= -1
Answer:
Irrational numbers are non-repeating and non-terminating
Hope that helps!
Step-by-step explanation:
Answer:
m = 4
Step-by-step explanation:
16 + 2(5m - 8) - m = 36
Distribute :
16 + 10m - 16 - m = 36
Combine Like Terms:
9m = 36
Divide by 9:
m = 4
Divide the coefficient of
x
(not
x
2
) by 2, and then square that.
c
=
144
.
Explanation:
Divide the coefficient of
x
(not
x
2
) by 2, and then square that.
So for
x
2
−
24
x
, dividing
−
24
by
2
gets us
−
12
.
Squaring
−
12
gets us
144
,
So
c
=
144
.
In general:
Consider the factoring identity
(
x
−
a
)
2
=
x
2
−
2
a
x
+
a
2
If we only have the middle term,
−
2
a
x
, then dividing the middle term by
2
x
gets us
−
2
a
x
2
x
=
−
a
(If we only take the coefficient on
x
, we do not have to divide by
x
.)
Then if we square that, we get
(
−
a
)
2
=
a
2
So as you can see, taking the coefficient on
x
, dividing it by
2
, and then squaring it will get us the magic constant that lets us complete the square.
